Having followed the DotNetNuke 4.0 module development tutorial as it came in the pdf with my DNN download, I uncovered an error in the code listing for SqlDataProvider.cs. It lacks a class definition section which can be found here: http://adefwebserver.com/DotNetNukeHELP/DNN4_SurveyModule/Survey_Module3.htm

After getting the site to build, I have found a problem with the sql scripts. I will try to resolve this tomorrow.

Got the module running, but it seems like it fails to add or retrieve data, as it fails to register answers to my surveys. Also I get a critical error: "value cannot be null. parameter name: String".

I have now gotten both my single choice and multi choice questions to work as long as there are no more than ten questions (indexed 0 through 9) by substituting all : with $ and appending a 0 behind ctl to make it ctl0 in the section that constructs the indexes for the Request.Form array. Obviously I have to add a control structure to decide if it needs a 0 behind ctl or not. But I am unsure if I am going to do that - I have achieved what I set out to do by making a module work. Since I know what's wrong with it, fixing it would probably be a waste of time now. But I guess what I have found will be helpful to the dotnetnuke community if the authors would like to correct the source code.

What's next for me in my project I don't know, but I will surf around a bit to find out.
